Oracle SQL到SAS企业指南

Question

您好我正在尝试将Proc Sql改编为SAS企业指南，我在使用OVER / PARTITION BY功能时遇到了一些问题。我收到语法错误消息，有人可以指导我这个吗？是否可以在SAS上运行它？

proc sql;
         create table NACIONAL as
           select distinct AÑO,
                            MES,
                             TABLA_ORIGEN,
                                Sum(Sum(flag)) OVER ( partition BY AÑO 
                                    ORDER BY MES rows UNBOUNDED PRECEDING) AS siniestros_total 
                    FROM   (SELECT NRO_SINIESTRO, 
                                   MES, 
                                   AÑO, 
                                   CASE 
                                     WHEN Extract(month FROM MES) = Min (Extract(month FROM MES) 
                                          OVER (partition BY NRO_SINIESTRO, Extract(year FROM AÑO)) 
                                        THEN 1 
                                     ELSE 0 
                                   END                               AS flag

列siniestros_total应按月执行累积计数，并应每年重新启动。
